Percutaneous interspinous distraction device for the treatment of lumbar spinal canal stenosis: clinical and radiographic results at 2-year follow-up.

Yingsakmongkol W, Chaichankul C, Limthongkul W - Int J Spine Surg (2014)

Bottom Line: The mean VAS score of back pain decreased significantly (p < 0.05).The device offers significant decrease in back pain, leg pain and ODI score with 2-year lasting relief from symptoms.A very weak correlation between the radiographic changes and improvement of pain was found.

ABSTRACT

Objective: To evaluate the effectiveness of the In- space (Synthes, Umkirch, Germany) and the correlation between radiographic parameters and clinical outcome in patients with lumbar spinal canal stenosis (LSS).

Methods: Between June 2009 and May 2013, 56 patients with LSS underwent In-space by one senior surgeon. All of the patients were evaluated both clinically and radiographic measurements before the procedure and each visit at the postoperative follow-up. Preoperative and postoperative X-ray imaging was performed before the procedure and at follow-up to assess the correlation with the clinical outcome. Radiological measurements and clinical outcomes were recorded to establish a relationship between the radiographic parameters and clinical outcome of this procedure. All patients had at least 2 years of follow-up.

Results: The mean VAS score of back pain decreased significantly (p < 0.05).

Conclusions: Our data suggest that percutaneous interspinous devices are a good alternative to treat LSS. The device offers significant decrease in back pain, leg pain and ODI score with 2-year lasting relief from symptoms. The increased intervertebral foramenal space explains the improvement of leg pain, but the mechanism of back pain relief remains unclear. A very weak correlation between the radiographic changes and improvement of pain was found.

Figure 0002: Postoperative X-ray (AP, Lateral, Extension and Flexion) of implanted In-space in the level L4-L5.

Mentions: With the patient in prone position, once the segment to be treated was identified under fluoroscopic guidance. An approximately 1.5-cm incision at right or left side was performed over the pathologic segment. All patients were administered antibiotic prophylaxis (1 g of Cephazolin) once per day starting from the day of the procedure. In addition, the operating time during operation and complications were recorded. The Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) were used for evaluate pain and functional assessment. Patients underwent serial follow-up evaluations. Two-year follow-up data was obtained in all patients. At each follow-up visit, patients were evaluated both clinically and radiographically. Radiographs (Figure 2) were obtained at immediate postoperative and 1 week, 1 month, 3 months, 6 months, 9 months, 12 months, 18 months and 24 months afterwards. Only patients who have completed a minimum follow-up period of 2 years were included in this study.
